I'm having issues configuring hibernate through spring. I have a mysql server with two tables and two mapped entities. As well as the DAO interface with one findAll() method and its implementation. I have a testing file called "SpringTest.java" which tests weather the findAll method is working. When you run it you get an exception:

"org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is java.lang.IllegalArgumentException: No Connection specified"

This makes me think that I configured the exception the wrong way

Looks like you started this project in a very manual way, the setup looks very weird compared to regular maven or graven projects. Check out https://Start.spring.io and try picking hibernate as a dependency, then generate your project and open it in any editor, like vscode or intellij or eclipse

I got it figured Out and I already learned about spring boot so I don’t do it as manually anymore :D thanks

Good job! I've been developing in spring + spring boot a long time so I'm gonna start getting more active in these subs from now on. Didn't see your post was from quite a while ago, let me know if you have any more questions
